Abstract: ABSTRACT OF THE DISCLOSURE         Described herein is a process to produce ammonia from hydrocarbon feedstock, involving basically the steps of dividing the feedstock into two fractions; subjecting the first fraction to a primary steam reforming reaction, at high pressure and moderate temperature; combining the effluent from the primary reforming with the second fraction of the feedstock, and subjecting the mixture thereof to a secondary adiabatic reforming reaction with an amount of air in excess of that needed for ammonia synthesis; subjecting the synthesis gas produced to a CO shift conver-sion reaction, and then to CO2 removal by solvent scrubbing, the gas released by pressure letdown of said solvent being preferably recycled back upstream of the secondary re-forming; -methanating the residual carbon oxides; -removing the excess nitrogen contained in the synthesis gas by cryogenic separation; -compressing and feeding the final synthesis gas into an ammonia synthesis loop; and -recycling the purge gas from said ammonia synthesis loop to upstream of the cryogenic separation.      This process achieves a substantial saving in energy as compared to conventional processes for preparing ammonia synthesis gas.

Abstract: TEA LASER CONFIGURATION     Abstract A transverse excitation atmospheric pressure laser employing a preionizing flash board formed on one of the sides of the laser tube.  The side wall of the laser tube acts as an insulating support plate having a backing plate on the outside surface and a set of subsidiary electrodes on the inside surface.  The subsidiary electrodes are short cylinders bonded to the inside surface of the support plate and having a flanged portion at the opposite end.  The pre-ionizing discharge takes place between adjacent subsidiary electrodes in the region between the flanged portions and is thus removed from the support plate.  The material for the flanged portions has a high melting point and a low sputtering capability.      A U-shaped enclosure provides a grounded housing for all the high voltage components and also provides a path for the discharge currents.

Abstract: .theta.          METHOD  AND  APPARATUS  FOR  PRODUCING   CONTAINERS  FROM             THERMOPLASTIC  SHEET  MATERIAL     ABSTRACT  OF  THE  DISCLOSURE     A method of and an apparatus for producing containers from thermoplastic sheet material are disclosed. The sheet material is heated to its plastic state and clamped at its periphery. Then a moulding die is advanced substantially normally towards and against the clamped heated sheet ma-terial. The moulding die has a temperature below the tempe-rature of the heated clamped sheet material and is provided with a projecting peripheral portion and/or a recessed central portion directed towards the sheet material. By further ad-vancing the moulding die by a predetermined amount against the sheet material, this is deformed and shaped into the desired container. A cooling air flow is directed against the clamped heated sheet material in a region thereof adja-cent to the peripheral portion of the moulding die to avoid reduced wall thickness at the edge and corner regions of the container by excessive stretching  of the sheet material. Thus, stable containers of uniform wall thickness may be produced.

The housing is a framed sheet of plastic film having a linear fold disposed horizontally along the top of the array of cavities, which are aluminized to provide a reflective coating on the cavity surfaces.  A pair of lead-in wires from each of the lamps are connected to conductive circuit patterns on one side of a printed circuit board sandwiched between a set of tabs which run along the bottom of the front and back portions of the housing.  The bottom periphery of the housing is secured together by means of a plurality of staples having legs which extend through the front and back tabs of the circuit board and are clinched onto the exterior surface of the front tab.  The front portion of the housing includes a window area which lies in a plane offset from the front tab and joined thereto by a web.  A label comprising an adhesive-backed sheet of substantially opaque material is affixed to the front portion of the housing and disposed to cover both the staples and the web, the web covering providing selective shielding of light radiated from flashing lamps.  The back of the label can be reflective for redirecting shielded light toward the reflective cavities behind the lamps for subsequent redirection as usable light.

Abstract: Hughes 10 c/c SECURITY APPARATUS AND METHOD FOR A SELF-SERVICE                    FUEL PUMPING STATION            ABSTRACT OF THE DISCLOSURE             A self-service station where a number of parties, each having an individual operating key or card, can pump gas from a single pump by inserting the key or card into a matching slot to activate the pump.  When the fuel begins to flow to the discharge nozzle, a pulsing device is activated to register on a counter the amount of fuel pumped.  To prevent pumping of fuel under circumstances where the pulsing device is not operating, there is a timer that shuts off the pump if the pulsing device does not become operative after a certain period of time.  The timer is arranged with a flow responsive switch so that the time period is measured from the time fuel actually begins to flow to the time that the pulsing device starts to operate.  This permits the time period to be made relatively short to minimize the pumping of fuel without recording the same on the counter.

A tight hermetic skin surrounds and encapsulates the body with the capsules in the holes and the conductors on the faces.  A pair of respective wires extending through the skin and connected to the conductors serve for passing electricity through the heating capsules.  The skin effectively protects the assembly from moisture when installed in a heater.  In addition this skin protects the heating element prior to installation and can in fact eliminate the need for a shipping package.

Abstract: SURGE PROTECTION FOR SIGNAL TRANSMISSION SYSTEMS   Abstract of the Disclosure Secondary surge protection means for equipment connected to transmission lines, for example line-powered amplifiers interconnecting Tl or TlC telephone lines, includes two diode bridges and a pair of surge diverters.  One diode bridge has its cathode/anode nodes connected one to each conductor of an incoming transmission line.  The other diode bridge is connected in like manner to an outgoing transmission line.  Each surge diverter interconnects the anode/anode node of one bridge and the cathode/cathode node of the other bridge.  When a surge on one line causes the voltage across one or other diverter to exceed a predetermined threshold, the diverter conducts, shunting the surge past the amplifier to dissipate in the other line.  The two transmission lines may be coupled to the input and output, respectively, of one amplifier, or to the input of one amplifier and the output of a different, oppositely connected amplifier.  In both cases, power for the or each amplifier may be derived from the two lines, for example by a Zener diode interconnecting them in known manner.  The characteristics of each surge diverter are such that it will respond to fast rise-time lightning pulses yet tolerate long duration power surges, and will be operated by differential mode or common mode surges.                              - i -
